There are many solutions to add a shopping cart to an online sales site. You may want a highly customized shopping cart for your portal, so you will need to hire the specialized services of a software programmer.
There are many online merchant solution service providers and they can set up your shopping cart and payment gateway software in a few days, but it will definitely come at a cost.
Then there are free online business solutions, such as the many online payment services. PayPal is one of these solutions and it is very reliable.
With the free solutions for online merchants available, there is no need to pay upfront. These services charge a percentage of the payments you receive online.
They have out-of-the-box software that is easy to install on your website. You just have to fill out an online form that asks for some details about your business and payment procedures.
They will provide you with the software code which is generated instantly. You just have to copy and paste this code into your website’s html code.
The online payment processor will also guide you on how to proceed. When you are done, you will be able to accept customer payments by credit and debit cards. The difference with free payment processors and custom online shopping software is that the money won’t be deposited directly into your bank.
The payment will go to the account of the free online payment processor and you will have to withdraw it from there to your bank account, for which there will invariably be a charge.
These are good solutions for small online businesses as they make up for the huge software development costs.
